Katy Perry claims most of her former boyfriends were "threatened" by her success.
The 'This Is How We Do' hitmaker, who is dating music producer Diplo and was previously in relationships with John Mayer and Florence And The Machine guitarist Rob Ackroyd, says she has "less time for bulls**t" as she approaches her 30th birthday on October 25.
The singer told the October issue of Harper's Bazaar magazine: "A lot of times I've ended up with people who have been intimidated by me, unfortunately. They say they're not, but it comes out in the long run. They're threatened, or there's resentment because they don't know how to handle it."
She added: "As I'm heading into my 30s I have less time for bulls**t. I look for the same characteristics: a sense of humour, someone who makes me laugh off the charts, someone who is sensitive, someone who loves and understands music, and who is really smart."
But Katy, who split from ex-husband Russell Brand in December 2011 after 14-months of marriage, has learned a lot from her past relationships.
She said: "I had to learn about taking care of myself before I could take care of others. I want to mommy everyone. I want to take care of them. I want to save them, and I forget myself in the meantime. I learned that through therapy."
The brunette beauty wants to focus on her career instead of settling down, but feels pressure to start a family.
She said: "Why am I a baby machine? Why can't I be a mogul? I want to have a baby, sure, but I want to have a career. I want to have a record label. I want to have an incredible tour. So I'm going to have all of those things. Let's talk about that. It's like, get off my ovaries, okay? I'll do it in time."
